mohs surgery

I have a dermatology question/concern.I had Moh’s surgery(all clear) on Jan 2 without stitches. On Jan 10 my surgeon said it was healing nicely. On Jan 22 a bump formed on the site. My question is: Is this the normal healing process without stitches? It is a bit worrisome. Surely the cancer couldn’t come back after only 20 days or could it. It stayed flat for the 6 weeks between the biopsy and surgery, and now there’s a bump after the all clear. Thanks
